No pictures of the plate before installation, sorry.

It sits in front of an airbox cavity that allows a back eddy to form. You can see a plastic edge along the bottom that the plate follows. The plate sits vertically and the fit requires a little trial and error fashioning. I used cardboard first.

Does it work?

The intent is improve top end air/fuel mixture. If this was dynoed I would expect to see a change in the power curve. I haven't done any testing, except by the seat of my pants. :)

The mod didn't hurt anything, but I honestly can't say that it improved anything. I can say that power delivery is smooth and steady getting to 90+ mph and that is good enough for me.

My homemade design may be less than optimal. I fashioned a rather sharp bend as this was my first attempt. A more gradual bend may result in better air flow.

I also created an air intake cutout in the side panel that is a straight shot into the main cavity of the airbox (there is a picture of this), relying less on the portion of the airbox intake toward the rear of the bike.
